Angular contact bearings are assembled to a contact angle by varying the radial clearance.
Spindle size Barden angular contact bearings have nominal contact angles of either 15° or 25°.
The smaller angle delivers better radial capacity and rigidity, the larger angle is better for
axial rigidity.

Separable and nonseparable types are available. In a separable bearing (B type), the cage holds
the balls in place so that the outer ring assembly (with cage and balls) can be separated from the
inner ring.

Deep Groove Instrument Bearings
Deep groove ball bearings have full shoulders on both sides of the raceways of the inner and outer
rings. They can accept radial loads, thrust loads in either direction, or a combination of loads.

The design of deep groove bearings make them suitable for the addition of closures which help
exclude contaminants and retain lubrication. Besides single deep groove bearings with closures,
Barden also offers duplex pairs with seals or shields on the outboard faces.
